Pacific Island Ecosystems Research Center
This is our office.
These are our co-workers.
This is our rush hour.
This is our pau hana.
Research at the Pacific Island Ecosystems Research Center focuses on providing the scientific understanding and technologies needed to support and implement sound management and conservation of our Nation's biological resources occurring in Hawai'i and other Pacific island locations.

Caly isn't likely to wonder off off, but with a remote camera and monitoring station online 24-hours a day, USGS and partners at the State of Hawai‘i Division of Forestry and Wildlife, University of Hawai‘i, and the USFWS can learn how an extremely rare plant is responding to changes in environmental conditions.
Dogs have great olfactory abilities and wildlife biologists think they can help endangered waterbirds in Hawai‘i. Dogs are being trained to sniff out the endangered ducks (koloa maoli (Anas wyvilliana) and Laysan ducks (A. laysanensis)) that die of avian botulism.
Forest birds on the island of Hawaii are responding positively to being restored in one of the largest, ongoing reforestation projects at Hakalau Forest National Wildlife Refuge, according to a new study released July 10 in the journal Restoration Ecology.
Invasive rat control is an efficient, yet insufficient, method for recovery of the critically endangered Hawaiian plant hau kuahiwi (Hibiscadelphus giffardianus)
Biological invasions of rodents and other species have been especially problematic on tropical islands. Invasive Rattus rattus consumption of Hibiscadelphus giffardianus (Malvaceae; common Hawaiian name hau kuahiwi) fruit and seeds has been hypothesized to be the most-limiting factor inhibiting the critically endangered tree, but this has not been...Gill, Nathan S.; Yelenik, Stephanie G.; Banko, Paul C.; Dixon, Christopher B.; Jaenecke, Kelly; Peck, Robert
Multi-state occupancy models of foraging habitat use by the Hawaiian hoary bat Lasiurus cinereus semotus
Multi-state occupancy modeling can often improve assessments of habitat use and site quality when animal activity or behavior data are available. We examine the use of the approach for evaluating foraging habitat suitability of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) from classifications of site occupancy based on flight...Gorresen, Paulo Marcos; Brinck, Kevin W.; DeLisle, Megan A.; Montoya-Aiona, Kristina; Pinzari, Corinna A.; Bonaccorso, Frank
Long-term impacts of exotic grazer removal on native shrub recovery, Santa Cruz Island, California
A combination of overgrazing and exotic species introduction has led to the degradation of habitats worldwide. It is often unclear whether removal of exotic ungulates will lead to the natural reestablishment of native plant communities without further management inputs. I describe here my return to sites on Santa Cruz Island, California, 12 years...Yelenik, Stephanie G.
